BOTH of you wake up! Digital TV channels are NOT as wide as analog TV channels. Also, the digital TV signal is virtually immune to low level interference. If you look on the FCC database you can already find extensive use of the "in between" space between other radio services channel allotments. There are two-way radio systems, monitoring devices, various digital links and all sorts of other goodies, even radio astronomy. Currently on the spectrum chart you can find multiple frequency ranges allocated for several radio services.

For example, many automatically controlled radio systems are not allowed to be controlled by a link that is part of the primary radio channel. Telephone companies can fill this need the same way they have for the past 70 years - they sell dedicated lines meant for the remote control of communications equipment. The reason comm equipment cannot be remote controlled over its own radio channel is because if something goes wrong with that device that requires it to be shut down its radio channel may be compromised. Telephone lines don't use the radio link, its just a pair of copper wires connected to a switching device. We do this all the time in the broadcast and communications world.
